In the 1960s Boston City Hall popularized the New Brutalist
style for government buildings in the U.S. The style uses massive forms
with site cast concrete, which is left ruff, often with marks from wooden
formwork or texturing by hammer. The distinctly pidemporary effect provides
a stark pidrast to Old
Boston City Hall.

The architects of City Hall explain that the structure of the building is
suggestive of the workings of government. In this explanation the massive
brick plaza flows into the building where there are large public spaces.
The upper floors provide repetitive anonymous space for agencies, and the
bold middle section is for the elected officials who are the conduits between
bureaucrats and the public.

The result is an uncharacteristically desolate building. Its massive brick
plaza provides space for open air concerts, and space to celebrate the sporadic
success of Boston sports teams. But in the end, celebrants move on the a
more hospitable subway stations.

Little
known fact: Kallman (from Germany) and McKinnell (from Britain), who have
not yet known Boston's "living puritanism", had hoped to establish a beer
hall in the Boston City Hall's basement like those in Germany city halls.
(This kind of feature would have undoubtedly been used to the advantage
and delight of several previous Boston Mayors.)
